 NeoPac Lighting has received a major national award, when the company’s NeoBulb Combo series - Lotus Pro RGB Lantern won in the “Best Product Design” category in a major competition for China’s LED industry.
"It is a major endorsement for our LED technology," said Jeffrey Chen, CEO of NeoPac Lighting. "This indicates our engineering know-how and design excellence are getting their due recognition. It is a high honor for the company, and is a distinguished achievement for all our R & D engineers involved."
He stated that ultra-high-power 54-watts “Lotus Pro” can provide RGB-mixing white lighting illumination at 1,350 lumens, and is a key product development for the NeoBulb Combo series produced by NeoPac Lighting.
All the entries for this “China National Solid State Lighting Design and Application Competition” were judged on five primary criteria – design originality, aesthetic quality, technical innovation, practical application, marketing and consumer acceptability.
The judging panel consisted of invited industry experts and key officials of the China National Solid State Lighting Policy Committee.
The award presentation was mad on July 13 at an official ceremony event during the 2006 China International Forum on Solid State Lighting in Shenzhen.
Taking place for the first time this year, the inaugural “China National Solid State Lighting Design and Application Competition” is to become an annual headline event for the LED lighting industry in the Greater China region, according to the forum organizing committee.
The Lotus Pro RGB Lantern won the award due to its combination of ultra-high power LED lighting, technical innovation, and overall design excellence.
It also blends modern mechanical construction with classic cultural elements of the lotus flower and the octagonal "Ba-Gua" pattern. Thereby it is a symmetrical-balanced “Lotus Lantern” design for the best geometric solution of heat management by the 9 proprietary system-in-package heat pipe based thermal modules.
Developing its own in-house LED packaging, NeoPac is at the forefront of solid-state lighting with 8 power chips (RRGGGGBB) on each of the 9 single-point-light source NeoPac Emitters.
The Lotus Pro RGB Lantern thus can provide 54 watts total for general illumination applications, with high brightness output on RGB-mixing white as well as in variable single colors.
It is this proprietary single-packaged and system-in-package design that empowers the “Lotus Pro” to achieve the high luminous flux and RGB-mixing white for general illumination.
Single color lighting is available for red, green, blue and also mixed colors at high lumen output.
Chen explained the ultra-high-power output is achieved with NeoPac’s system-in-package technology, “We can control the RGB chips junction temperature (Tj) inside NeoPac™ Emitter under 60°C,with the ambient temperature (Ta) at 25℃."
"It is a crucial issue for keeping the high power (6 w) RGB junction temperature at such low level since the decay rate of blue, green and red chips are quite different at high junction temperature. It is the hurdle for high power RGB package application for general lighting.” |

NeoPac releases ultra-high-power RGB-based point-light-source LEDs for general illumination |

 NeoPac Optoelectronics, a subsidiary of NeoPac Lighting, has recently launched a world leading system-in-package, ultra-high-power, point-light-source RGB-based LEDs component for all-purpose color lighting requirements.
NeoPac integrates its proprietary first-level LED packaging (NeoPac® Emitter) and second-level high-efficiency heat sink (NeoPac® Thermal Module) into a revolutionary system-in-package component, called “NeoPac® Light Engine”.
The E47V012-NE NeoPac® Light Engine (see photo), as the core component of new styled LEDs general lighting fixture, can provide high-brightness output in mixing white (6 Watts, junction temperature Tj < 60℃), red, green, and blue in single color as well as mixed colors on demand. This is the world’s latest LEDs package revolution for realizing RGB mixing white light applications for general lighting.
Jeffrey Chen, CEO of NeoPac Lighting said “It is a breakthrough technology for empowering the single-packaged RGB Light Engine at 6 watts for mixing white, and control the RGB LEDs junction temperature under 60℃ as well. It is a crucial issue to keep RGB light source at such low Tj since the decay rate of Red, Green, Blue chips in same package are different, particularly at high junction temperatures. It was always a challenge for the RGB approach to compete with pc-White solution for general lighting application. By having our system-in-package RGB solution, we see a bright future in RGB-based LEDs lighting market”
Since the system thermal resistance, Rja (from LEDs junction to ambient), of this NeoPac® Light Engine is only 5.8℃/W, the temperature difference between LEDs junction and ambient air is only 35℃. If the application keeps the LEDs junction temperature at 120℃, the E47V012-NE NeoPac® Light Engine can overdrive up to 16 Watts.
As part of NeoPac® Light Engine, the patented NeoPac® Emitter is a single package format with eight 40mil x 40mil power chips (RRGGGGBB), using flip-chip technology to fix on a silicon submount which is supported by a proprietary NeoPac-designed hollow LTCC chip carrier. The high-density RGB multi-chips module attaches directly on the flatten end of a micro heat pipe that is surrounded by stacked aluminum dissipation fins, each at 40mm in diameter. The heat pipe-based NeoPac® Thermal Module coupling with NeoPac® Emitter can take the heat out efficiently from LEDs chips to the surrounding air.
“We can say that the E47V012-NE NeoPac® Light Engine is a 16-Watt package (Tj at 120℃ as ambient temperature at 25℃) or it is only a 6-Watt package (Tj at 60℃ as ambient at 25℃) for general lighting purpose. When we talk about the LEDs power dissipation, we have to talk about the corresponding LEDs junction temperature as well. It is a very important concept for the definition of LEDs power dissipation since Tj is a crucial issue for general lighting application. Controlling the junction temperature is very important to LEDs system integrators. It is also a critical barrier for high-power LED package and module assembly houses. In high power LED application, too much heat will degrade the RGB chips and the lighting-emitting source components. It would also shift their spectral characteristics, and this alters the chromatic color output,” Jeffrey Chen states.
Chen said this new packaging solution can provide a new direction for the industry and eventually improve a cost-down value-chain infrastructure for LED lighting.
He pointed out that the NeoPac® Light Engine is also a basic building block for the “NeoBulb™ Universal Platform”. NeoPac Lighting has formally launched the platform and demonstrated a number of new LEDs lighting devices (NeoBulb and NeoBulb Combo) at the Lightfair International exhibition, in Las Vegas in early June.
The NeoPac® Light Engines and its combination product series are thus well-suited to provide high-brightness output and high power lighting for consumer use, industry and residential settings needing applications in color illumination and general lighting.
